Same here on HKG fare. It used to be my gateway into Asia, but fares have literally doubled in price in the past couple of months. It seems odd on a route that is typically priced low due to so much competition. AFAIK no carrier dropped their HKG route so this is... strange.
I've been monitoring fares int he past week hoping for a last-minute deal for the 4th holiday but no luck. HKG, NRT, SEA, ANC, YVR, everything is more expensive now.
